ROB. B. LEWIS, OF HALLOVELL, MAINE.

MANNER 0F ATTACI-IING BRISTLES TO THE STOCKS OF BRUSHES FOR WHITEWASI-IING AND SUCH OTHER PURPOSES.

Specification of Letters Patent No. 1,992, dated February 23, 1841.

To all whom if may concern Be it known that I, ROBERT B. Lnwrs, of Hallowell, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Brushes for lVhitewashing and Such other Purposes to lVhich the Same may be applicable.

lIhe said improvement, the principles thereot1 and manner in which I have contemplated the application of the same, by which it may be distinguished from other inventions, together with such parts or combinations I claim as my invention, I have herein set forth and explained in the tollowing description and accompanying drawings, which taken in connection form my specification.

Figure l, is a vertical cross section of my improved brush, Fig. 2 being an elevation and Fig. 3 a longitudinal-vertical section.

The usual method of conining the bristles in a brush for whitewashing and such like purposes is by a band of leather or metal surrounding and tacked to a rectangular block of wood, between which and the said band the bristles are conlined. It will readily be apparent that this is a very ineflicient way of confining the bristles and also that the operation of a brush so formed is somewhat defective, the divisions on the bristles (necessarily occasioned by the insertion of the nails) having a tendency to lav on the white wash or color in stripes as may frequently be observed, which destroys the beauty and finish of the work.

The object of my improvements is to efectually remedy these defects and to provide, as it were, a framework in which new bristles may be inserted at a triiling expense after the old ones become unfit for use.

A plug a Fig. 1, is inserted in the bottom of a cylindrical tube bFto the top of which aA handle is connected by means of a slot and bent catch (similar to the common umbrella. catch), as shown at -cn in Figs. 1, and 2. To the underside of the plug a is connected or attached the double-chamtered bar d d,

the section orp which would be somewhat elliptical (see Fig. l), and which is equal in length to the width of the brush. The blunt ends of the bristles to be used in the brush are placed on each side of the bar d (Z, and are confined there by means of a metallic band e e, which surrounds the bar (Z (l and bristles thereon. This band e e is halved or formed of two parts, which are united, at the sides of the brush, by means of common hinge joints through which pins are passed as shown at f f Fig. 3, and each of the said parts is connected or secured to the handle by screws g g passing through the ears /L i and tube b into the plug a. From this arrangement it will be seen that after the heads of the bristles are cemented together by any suitable glutinous substance, itl would require considerable :torce to remove even one from the body or brush; inasmuch as the band e e binds very irmly on the protruding parts of the bar l d, which would not permit it to pass. It will likewise be seen that by removing either of the pins 7 f, the old bristles may be thrown aside and new ones inserted, at a comparatively trifling expense.

Having thus described my improvements I shall claim as my invention as follows, viz:

Coniining the bristles in a brush, (more etfectually than heretofore) by means of a double chamfered bar, (whose section would be elliptical and on which the bristles are placed), in combination with the metallic band e e, which is formed of two parts united by joints and pins as described, the whole being arranged substantially in the manner and for the purposes above set forth.

In testimony that the above is a true description ot my said invention and improvement I have hereto set my signature this thirteenth day of August in the year eighteen hundred and forty.
